Like many sci-fi, science, and space geeks, the exploration and colonization of Mars has always held a special fascination for me. Shannon Sproule has created a LEGO version of a novel idea — sending a drone to 3D print habitats on Mars. With a realistic color scheme and extensive use of round bricks, including a pair of round 7×7 domes, Shannon has created a plausible construction robot. Here’s hoping NASA is paying attention to innovative ideas like this!
